Google-jacking?

[Dave Temkin <dave () ordinaryworld com>]

Has anyone seen a situation on their internal networks where going to a
(non-Google) page "Hijacks" them and they end up with either the Google
front page or a broken link page?

This happens on machines both with the toolbar and without, and we've
seen it on machines on different networks/running different OS's.

Just curious.
Thanks,
-Dave
